Update usermods: FixUnreachableNetServices and PIRsensorSwitch (#1448)
* Removed usermod Fix_unreachable_webserver

* Changed README. Added a compiler warning for ESP32

* Fix ESP32 compiling issue. Add instance ptr API.

* Updated usermods. Store config values. ESP32 fix.

* Store analog clock settings

* Rename JSON values

bring them visually more in line with the other settings

/*
* This usermod handles PIR sensor states.
* The strip will be switched on and the off timer will be resetted when the sensor goes HIGH.
* When the sensor state goes LOW, the off timer is started and when it expires, the strip is switched off.
*
*
* Usermods allow you to add own functionality to WLED more easily
* See: https://github.com/Aircoookie/WLED/wiki/Add-own-functionality
*
* v2 usermods are class inheritance based and can (but don't have to) implement more functions, each of them is shown in this example.
* Multiple v2 usermods can be added to one compilation easily.
*
* Creating a usermod:
* This file serves as an example. If you want to create a usermod, it is recommended to use usermod_v2_empty.h from the usermods folder as a template.
* Please remember to rename the class and file to a descriptive name.
* You may also use multiple .h and .cpp files.
*
* Using a usermod:
* 1. Copy the usermod into the sketch folder (same folder as wled00.ino)
* 2. Register the usermod by adding #include "usermod_filename.h" in the top and registerUsermod(new MyUsermodClass()) in the bottom of usermods_list.cpp
